Answer:
Step-by-step explanation:
The ratio of the number of fiction books is 9:4
the difference between the number of fiction and nonfictionn is 245
so if the number of fiction books = 9x
then the number of nonfiction books = 4x
then difference = 9x-4x = 5x
the difference is given 245
then 5x= 245
x==49
number of fiction books =49×9=441
number of nonfiction books =49×4=196

The inclination to the nearest tenth of a degree exists 0.24146
<h3>What is the inclination to the nearest tenth of a degree?</h3>
The given scenario includes a right-angled triangle where the length of the ramp exists hypotenuse and the rise of ramp exists the perpendicular.
Given: H = 4.6 m and P = 1.1 m
We have to use the trigonometric ratios to find the angle. The ratio that has to be used should involve both perpendicular and hypotenuse
Let x be the angle then
sin x = P/H
sin x = 1.1/4.6
sin x = 0.23913
= 0.24146
The inclination to the nearest tenth of a degree exists 0.24146

If the exponential function passes through the points (3,25) and (8,10), the value of b is 0.833
The given exponential equation is:
The function passes through the points (3, 25) and (8, 10)
Substitute x = 3 and y = 25 into the function
............................(1)
Substitute x = 8 and y = 10 into the function
.............................(2)
Divide equation (2) by equation (1)
Therefore, if the exponential function passes through the points (3,25) and (8,10), the value of b is 0.833
